Specification of Letters Patent.

Patented Oct. 19, 1915.

Application filedAprii 29, 1913. Serial No. 764,300. I

To all whom it may concern.

Be it known that I, CLio B. YAW, citizen of the United States, and resident of Arlington, in the county of Hudson and State of New Jersey, have invented certain new anduseful Improvements in Type-Writing Machines, of which the following is' a specification.

My invention relates to paper cutting and controlling devices for typewriting machines and its object is to provide new and improved devices of the character specified, the novel devices being especially useful in systematically cutting short strips or sections from a continuous roll or web although of course not restricted to such use.

To the above and other ends my invention consists in the features of construction, combinations of devices and arrangements of parts hereinafter described and particularly pointed out in the claims.

My invention is applicable to typewriting machines generally, but the preferred embodiment. herein illustrated has been applied to a No. 10 Remington typewriting' machine as shown in the accompanying drawings, wherein Figure 1 is a fragmentary end view, partly in section, of the upper portion of a No. 10 front strike Remington typewriting machine embodying my invention. vFig. 2 is a fragmentary plan view of the same. Fig. 3 is an enlarged transverse sectional view taken on a plane indicated by the dotted line a in Fig. 2, the pivotal cutting blade being shown moved to a position to partially cut the paper.

The main frame of the machine comprises posts l supporting a top plate 2 above which are secured grooved guide rails 3 which cooperate through anti-friction balls with the grooved front and rear bars, numbered respectively '5 and 6, of a truck which further comprises end bars 7. Supported on the truck is a platen frame comprising end bars 8, said end bars being connected by cross bars or rods of which the rearmost two are illustrated and numbered 9 and 10.

The traveling platen carriage or carrier comprises said truck and said platen frame, said frame pivotally supporting a platen 11 and being shiftable up and down on the truck to change case, although in the present instance I prefer to set the platen frame in fixed relationship with the truck, as in the special character of work for, which the present invention is more particularly designed, only upper case types are employed. Ope'ratively connected with the right-hand end of the platen 11 is a line spacing ratchet wheel 12 with which cooperates a spring mounted roller detent 13. Line spacing movements are communicated to the platen by devices comprising a pawl 14 pivoted on an arm 15 which in turn is pivoted to swing about the platen axle 16, as an axis, said pawl being operative by a train of devices comprising a link 17 which connects it with a bell crank 18, said bell crank being connected by a link 19 with a crank arm 20 on a rock shaft 21 which turns in a housing 22 mounted on the carriage truck. The rock shaft terminates in a downwardly extend; inghandle or finger piece 23 which is operative to actuate said pawl 14 to line space the platen and also concurrently to restore the carriage from left to right to begin a new line of writing.

Mounted on the carriage is a paper supply roller or'spool that comprises both a core or .on a support or frame comprising parallel end bars or arms 27 and a connecting cross bar 28, the upper ends of the arms 27 being slotted as indicated at 29 to receive the end or bearing portions 24 of the supply roller. The arms 2 are formed with holes through which the rod 9 of the platen frame passes and at their lower ends said arms are slotted, as indicated at 30, to cooperate with the frame rod 10. The support or frame comprising the arms 27 is adjustable lengthwise of the platen, being confined between adjustable collars 31 which are set on the rod 9. The paper 26 is drawn oil from the supply roller at the rear side and led around and up at the front side of the platen to the severing devices hereinafter described, which are arranged above the platen. A friction spring 25 secured to one of the arms 27 cooperates 'with the adjacent flange 25 to prevent undue rotation of the supply roller. Between the severing devices and the supply roller or spool, paper guiding devices are arranged, said devices including a guide bar 32 which is adj ustably mounted onthe arms 27, said bar 32 being slotted near its ends as indicated at 33, the slots receiving clamping screws 34 which screw into the arms 27, the construction affording an adjustment of the bar 32 lengthwise of the platen. Mounted on the bar are marginal guiding devices or lips 35 which extend inward toward each other, the paper passing over said bar and under said marginal devices 35, which latter may, if dc,- sired, be the inturned end portions of a separate piece suitably secured to the bar 32.

The paper shearing or severing devices or elements are mounted on a support or bar 36 which in turn is mounted on the carriage or carrier, being secured to the end bars 7 of the truck. The bar 36 extends longitudinally of the platen and is arranged above the platen and forward thereof. In order to position the bar in the desired location it is mounted on short posts 37 arranged in pairs on the end bars 7 and each threaded at its upper end, as indicated at 38, to receive pairs of nuts 39 between which the bar 36 is clamped at its end portions. As is apparent the construction is such that the vertical position of the support or bar 36 may be varied by adjusting the nuts 39 on the threaded portions of the posts 37, thus varying the position of both the bar and the cuttin devices mounted on it in respect of the printing line on the platen. At its right hand end the bar 36 is offset forward, as indicated at 36, so as not to interfere with the line spacing mechanism. Secured to the upper face of the bar 36 in fixed relationship therewith by screws 40 is a severing member, device or blade 41, said blade ex tending along said bar with its sharpened or cutting edge at the rear side. A cooperating cutting device, member or blade 42 is pivotally supported above the rigid or relatively fixed blade 41, saidswinging or pivotal blade being pivoted on a shouldered screw or other suitable pivot 43 at or near its left-hand end, which pivot screwsinto and if desired through the underlying blade. Normally the blade 42 is swung rearward to the position shown clearly in Fig. 2, its cutting or sharpened edge being at the forward side facing the cutting edge of the rigid blade 41. When the blade 42 is thus disposed, the paper may pass upward between the printed on by the 006 erationof the types (not shown) with the ront or printing face of the platen. The rearward swinging movement of the blade 42 is limited by a lug or stop device 44 fixed to the bar 36 and cooperating with an inclined stop face 45 on the tail or rear portion of the blade. The stop devices 44 and 45 are normally maintained in engagement by spring means comprising a coiled spring 46, one end of which blades 41 and 42 after it has been" is anchored to a pin 47 on the bar 36, the

other end being hooked over a pin 48 on a finger or projection 49 which extends rearwardly from the blade at substantially right angles thereto. The tail portion of the blade 42 is provided also with a stop face 50 oppositely inclined from the face 45 and cotiperative with a stop device or lip 51 which is preferably turned up from the left-hand end of the blade 41. This stop device 51 coiiperates with the stop face 50 to limit the forward swing of the blade 42 and prevent excess movement in the cutting or operative direction. The pivotally connected blades 41and 42 are adapted toreceive relative swinging or pivotal movement with respect to each other, this movement in the present instance being brought about by swinging the blade 42 on its pivot by means operating automatically during the travel of the carriage, and preferably at a predetermined point in the return movement of said carriage. The automatic devices comprise a finger 52 extending forward from the blade 42 and atsubstantially right angles thereto, said finger being adapted to cotiperate with a stationary device, abutment or pin 53;which is secured to the free end of an arm 54, said arm'being secured to the left-hand side of the top plate 2 by screws 55 and extending inward toward the middle of the machine therefrom. The pin 53 extends upward sothat it intersects the path of the finger or projection 52 and when in the course of return movements of the carriage said projection engages said finger, the spring 46 will be overcome and the blade 42 will swing forward in a substantially horizontal plane co-acting with the blade 41' blade 42 swings is substantially horizontal.

Said guiding device comprises a short vertically disposed chute or guide" 56 having a forwardly extending lip 57 secured by screws 58 to the under side of the bar 36, the chute extending downward nearly vertically from said bar and substantially in line with the printing face of the platen and terminating a short distance above the printing line so that the paper passes into said chute or guide shortly after being printed on and leaves the chute at the top;

just prior to intersecting the path of the cutting blade 42.

they have been out, out of the way transversely of the unsevered paper and into the receptacle or contalner. The paper moving "means in the present instance comprises an abutment, blade or lip 59 which is turned upward at right angles from the body pore tion 60 that is secured by screws 61 to the top of the blade if 3. The moving device or means 59 extends longitudinally of the blade 42 and is arranged above its cutting edge and nearly in the plane thereof so that as the paper is cut during the cutting stroke of the blade 42 by the coiiperation of its edge with the blade i1, the severed or cut strip or. slip will be pushed forward by the abutment or device 59 and into the receptacle indicated as a whole as 62. This receptacle preferably is an open frame of sheet metal mounted on the bar 36 and comprising a horizontal portion 63 secured by the'screws 58 to the under side ofsaid bar below the lip 57. From the forward side of the horizontal portion the receptacle is bent upward to provide a front wall 64: terminating in ,rearwa-rdly inclined lips 65,

side lips or lugs 66 also being provided to' prevent endwise displacement of the paper slips during movements of the carriage. The vertical wall 64 is cut down as. indicated at 67 so as to facilitate the removal by hand of the accumulated slips from the receptacle. These slips, it will be understood, after they have been pushed one by one by the device 59 over the upper face of the blade 41 will drop down below the forward edge of said blade which is cut out as indicated at 41 so as to provide in connec tion with the front face of the bar 36 a low, rear wall or face for the receptacle.

As will best be understood from Fig. 3 the slips are supported in the receptacle on the bottom'face 63 and between the face 41 and the wall-6i. In said Fig. 3 the uncut portion of the paper extending upward through the chute 56 is omitted for the sake of clearness. The parts are so arranged that the paper web is cut midway between successive single line entries printed on it and it will be understood that after one line has been written the paper is line spaced and the carriage is drawn backward and during the backward or restoring movement of-the carriage the device will cooperate with the abutment to swing the blade 42 forward, thereby giving it a cutting stroke and causing it to coiiperate with the blade 41 to shear the paper below the uppermost entry thereon while concurrently the sevbe completed when the carriage reaches its limit of rightward movement. Thereafter as the carriage moves leftward during printing operations the blade 42 will be gradually swung back to normal position by the spring 46 which, of course, hasbeen' overcome and extended during the shearing operation.

My present invention is simple and inexpensive in construction, containing few parts and operates automatically to sever the work sheet periodically and systematically into convenient lengths or slips, also gathering these slips in order in a receptacle, receiver or container for convenient handling. By providing for a shearing cut I insure that the paper shall be severed cleanly, avoiding ragged edges and an ob-, struction of the operation which might occur as the result of imperfect cutting.

Various changes -may be made without departing from the spirit and scope of my invention. i
